Apple Music subscribers can download songs for offline listening, but this gradually consumes iPhone storage. The Music app includes a built-in feature called Optimized Storage that automatically removes older, unplayed tracks when space runs low. This helps free up gigabytes without manual intervention, ensuring you have room for new music or apps.

To enable it, navigate to Settings > Music > Downloads > Optimized Storage. Toggle the switch on and set a minimum storage threshold for your music library. Apple then manages downloads in the background, prioritizing tracks you haven’t played recently. This is particularly useful for users with 64GB or 128GB devices where space is at a premium.

For those who prefer manual control, you can disable automatic downloads and manage your library directly within the Apple Music app. Removing songs one by one offers more precision, though it requires more effort. This feature reflects Apple’s broader push to simplify storage management across its ecosystem, a common pain point for smartphone users.
